Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deodorizing device for separating odors emitted from pig farms, poultry houses, food manufacturing plants, and the like.

Conventionally, in order to remove odors from odor-containing gases, attempts have been made to filter the exhaust gas with filters or deodorize with deodorizers, but filters quickly become clogged, and deodorizers quickly clog. It had drawbacks such as being unusable.

The purpose of the present invention is to provide a deodorizing device whose technical concept is completely different from that of the conventional example. Utilizing the phenomenon that while the exhaust gas is swirling inside the main body, fine water droplets are ejected into the exhaust gas, causing the odor molecules to collide with the water droplets, and the two become one as a result of the collision. The basic technical idea is to separate odor molecules from the exhaust gas. Specifically, it uses a cyclone device, pressurizes the exhaust gas containing odors into the cyclone device, and injects pressurized water into the cyclone device. The odor molecules are ejected in a mist to combine with water droplets to increase the weight of the odor molecules, and the centrifugal force that acts on the odor molecules forms a combination of odor molecules and water on the inner wall of the main body of the cyclone device. The feature is that the odor molecules are separated from the exhaust gas by flying them to the air.

Next, embodiments of the present invention will be described with reference to the drawings.

10 is an odor molecule separation device, and 1 is a cylindrical main body. This separation device 10 is also a device that separates and captures odor molecules. A gas (exhaust) inlet pipe 2 is provided in the tangential direction of the main body 1, and an outlet pipe 3 having an opening 3a near the bottom of the main body 1 is provided in the center of the main body 1.

A water fountain pipe 4 is provided so as to surround the portion 3b where the outlet pipe 3 protrudes into the interior of the main body 1, and a water conduit pipe 5 into which water pressurized by a pump 6 is introduced from above is provided into the fountain pipe 4. are connected. The fountain pipe 4 is also provided with a large number of small holes 4a, and water pressurized by the pump 6 is sprayed into the main body 1 in the form of mist from the small holes 4a. Reference numeral 7 denotes a water tank connected to the water intake port of the pump 6, and a drain pipe 8 is provided at the lower end of the main body 1 to discharge water accumulated in the main body 1.

The introduction pipe 2 is an odor source 1 such as a pigsty.
1, and inside the introduction pipe 2 there is a fan 12 for pressure-feeding the exhaust gas into the main body 1.
is provided. Further, a return pipe 13 is provided which connects the suction side of the fan 12 and the outlet pipe 3.
A part of the purified exhaust gas in the outlet pipe 3 is returned to the suction side of the fan 12 by the return pipe 13 . In addition, Juan 12
It will be easily understood that the odor molecule separation apparatus of the present invention is of the same type as a cyclone apparatus, due to the main body 1 and the introduction pipe 2.

In operation, by driving the fan 12, odor-laden exhaust gas is moved from the source to the inlet pipe 2.
is press-fitted into the main body 1. The introduction pipe 2 is the main body 1
Since it is connected tangentially to the main body 1
The exhaust gas press-fitted into the main body 1 rotates within the main body 1 and is then discharged from the outlet pipe 3. At the same time, the pump 6 is activated to spray water into the main body 1 in the form of mist from the small hole 4a.

The water spouted from the small hole 4a is water pressurized by the pump 6 and is spouted from the small hole, so that extremely fine water droplets are ejected in the form of mist. Then, odor molecules contained in the exhaust gas circulating in the main body 1 bond to the ultrafine particles of water.

Since the odor molecules combined with the water droplets increase in weight, they are further subjected to the action of centrifugal force, thereby scattering outward and adhering to the inner wall surface of the main body 1. As such molecules fly onto the inner wall surface of the main body 1 one after another, they become one body on the wall surface, eventually fall naturally along the inner wall surface, and then drain from the lower end of the main body 1. It is discharged to the outside through a pipe 8.

In this way, the odor contained in the exhaust gas is captured by the water droplets and is discharged out of the device along with the waste water. Therefore, since the exhaust gas discharged from the outlet pipe 3 is clean and does not contain odor molecules, there is no risk of causing air pollution even if it is discharged into the atmosphere.

In this device, since the fan 12 is directly exposed to exhaust gas containing odor molecules, there is a risk that the fan 12 will become contaminated in an extremely short period of time. As a countermeasure against this, for example, a means is provided to return a part (for example, half) of the clean air in the outlet pipe 3 to the suction side of the fan 12 through the return pipe 13. As a result, the degree of contamination of the odor in the exhaust air sucked by the fan 12 is reduced, and the accumulation of odor components on the fan 12 can be reduced. In addition, since the odor concentration of the exhaust gas introduced into the main body 1 is low at this time, a secondary effect can be expected in that odor molecules are more effectively separated (captured by water droplets) within the main body 1.

FIG. 3 shows an embodiment of the deodorizing device of the present invention, in which a plurality of odor molecule separation devices shown in FIG. 1 are arranged in series, and the exhaust gas is sequentially passed through these devices. This allows for even greater cleaning. Note that in this example, the fan 12 is provided only in the introduction pipe of the first (leftmost in the drawing) separation device 10;
2 may be provided separately in each separation device, and the water tank 7 may also be separate rather than common.
Furthermore, it goes without saying that the exhaust discharged from the drain pipe 8 may be purified by a deodorizing device (not shown) and the water may be reused.

As described above, the present invention removes odor molecules from the exhaust gas by spraying fine water into the exhaust air and combining the water droplets with the odor molecules, so it is not necessary to use a filter. This eliminates filter clogging and pressure loss due to the filter. Furthermore, since the deodorizing device of the present invention utilizes the phenomenon of the capture of odor molecules by water, it has an extremely wide range of application and is extremely effective in practical use.
